A great number of Central Asian wall paintings, archeological materials, architectural fragments, and textiles, as well as painting fragments on silk and paper, make up the so called Turfan Collection at the Asian Art Museum in Berlin. The largest part of the collection comes from the Kucha region, a very important cultural center in the third to ninth centuries. Between 1902 and 1914, four German expeditions traveled along the northern Silk Road. During these expeditions, wall paintings were detached from their original settings in Buddhist cave complexes. This paper reports a technical study of a wall painting, existing in eight fragments, from the Buddhist cave no. 40 (Ritterhöhle). Its original painted surface is soot blackened and largely illegible. Grünwedel, leader of the first and third expeditions, described the almost complete destruction of the rediscovered temple complex and evidence of fire damage. The aim of this case study is to identify the materials used for the wall paintings. Furthermore, soot deposits as well as materials from conservation interventions were of interest. Non-invasive analyses were preferred but a limited number of samples were taken to provide more precise information on the painting technique. By employing optical and scanning electron microscopy, energy dispersive X-ray spectroscopy, micro X-ray fluorescence spectroscopy, X-ray diffraction analysis, and Raman spectroscopy, a layer sequence of earthen render, a ground layer made of gypsum, and a paint layer containing a variety of inorganic pigments were identified. 相似文献

This paper describes both theoretical and experimental studies on the application of a portable water mist extinguisher in suppressing flammable liquid and wood crib fires. At first, the interaction between water mist and fire plume is studied by analyzing the instantaneous process of fire extinction. And then, the feasibility in extinguishing diesel oil, gasoline and wood crib fires is studied by a series of experiments. Theoretical analysis and experimental results show that the extinguishing mechanisms and process change with the difference of water mist characteristics (such as water flux density, droplet velocity and diameter), and the portable water mist fire extinguisher with appropriate characteristics was able to extinguish Class A and Class B fires. It is a potential fire protection means for historical buildings. 相似文献

The history of using tiles in Persian architecture dates back to the eleventh century. In the beginning, tiles were made of bricks and mounted with plaster. Thereafter, however, tiles were replaced with mosaics to decorate buildings. The technique of applying mosaics began in the thirteenth century and reached its summit during the Ilkhanid and Timurid periods between the fourteenth to sixteenth centuries. One of the most outstanding buildings in which mosaics were widely used is Ghaffarieh Dome, a fourteenth-century building in Maragheh, Eastern Azerbaijan. The Dome is especially noteworthy for its unique mosaic workings. Therefore, a thorough examination of the mosaics used in the Dome may pave the way for closer studies of the Ilkhanid mosaics (tile-workings) in Iran. Since there is little information on the material aspects of mosaics used in the Ghaffarieh Dome, the body and glaze of the mosaics were examined through instrumental analyses. In order to interpret the results of the analyses, they were compared with existing data about similar mosaics of Islamic lands. The presence of pyroxene (aluminum diopside) in some of the mosaic bodies revealed that the firing temperature limit in the kiln was not, most likely, uniform. Two kinds of glazes, alkaline and lead-based, were used to produce black and turquoise colors. 相似文献
